Just to elaborate on the effect of the CPI escalation on the base price
Over a 10 year period the CPI might escalate 30-40%
If ARU negotiated a $1000 base price
In 10 years that same base would be in the $1300-$1400 range
A $1500 base could escalate to the $2000-2100 range
(ballpark figures only)
food for thought
